Detailed Product Information

Part number 99610662702 is a lower radiator coolant hose for the Porsche Boxster cooling system. It connects the return line to the return tubes on 1997-2000 Porsche Boxster models, making it a fitment-specific replacement for service work on the lower hose path. The molded EPDM design helps maintain shape under heat cycling and exposure to ozone, while the OE-style form supports proper routing in the engine bay.

Common Cooling System Issues

  • Coolant seepage at a cracked or aged lower hose
  • Softening, swelling, or hardening of the original rubber hose
  • Improper coolant return flow caused by hose deterioration
  • Heat-related hose damage from repeated thermal cycling
  • Electrolysis-related rubber breakdown in the cooling system

Installation Notes and Tips

Verify the hose routing against the original part before installation on your Porsche Boxster. Inspect adjoining return tubes, clamps, and nearby cooling components for wear, corrosion, or residue before reassembly. After installation, refill and bleed the cooling system according to factory service procedures and check for leaks at operating temperature.
